Abstract
A balanced-unbalanced conversion-type elastic wave device includes an unbalanced signal terminal, first and second balanced signal terminals, and first to fifth interdigital transducers disposed along an elastic wave propagation direction. One end of each of the first, third, and fifth interdigital transducers is connected in common to the unbalanced signal terminal, one end of each of the second interdigital transducer and the fourth interdigital transducer is connected to the first and second balanced signal terminals respectively, a first inductance is connected between the first interdigital transducer and a ground potential, and a second inductance is connected between the fifth interdigital transducer and the ground potential. First and second inductance values of the first and second inductances, respectively, are different.
